MAX3740: The MAX3740/MAX3795 Laser Driver Average Power Monitors (PWRMON)

Abstract: The MAX3740 and MAX3795 laser drivers provide a monitor output of the average optical power of a laser diode using a monitor diode current input from the laser assembly. This is often done in data communication type laser drivers. The implementation of this feature on the MAX3740 and MAX3795 is different than the conventional method used in other laser drivers which can lead to confusion regarding its use in an SFP module that implements the SFF-8472 digital diagnostics.
